Physical interface principles
We wanted to stay close to the basic concept of the mirror and therefore create effects by different arrangements of image sections and rotations. Our concept should be something that you could construct with a conventional mirror up to a certain point. In general, our goal was to keep the user engaged for a long time and let them discover the interactions through intuitive movements. For this objective we found a kind of kaleidoscope to be the optimal solution.
A kaleidoscope is made up of an even number of triangles arranged together in a circle. Two triangles next to each other form a pair that is mirrored. Each of these triangles shows a section of the video so that the person sees himself several times in front of the mirror.
In order for the user to interact with the kaleidoscope in front of the mirror, it must be recognized. For this purpose we used glasses with a coloured element. This yellow colour is tracked to determine where the person is and what movements they are making. The camera tracks the user's horizontal/vertical position and distance. Through the glasses, the user also has the feeling that the effects are only visible through the glasses, as they only start when the glasses are put on.
By moving the head in a horizontal direction, the color of the kaleidoscope changes in order of the color spectrum.
If you move your head vertically, the brightness of the color changes.
The closer you get to the camera with your head, the bigger the particles become. Polygons are formed at long distances and triangles at short distances.
By tilting your head you can also determine the direction of rotation of the kaleidoscope.
